  • Process for the oligomerization of ethylene
    Patent number: 4288648
    Abstract: Ethylene is oligomerized by contacting ethylene with a catalyst produced by contacting (a) a refractory metal oxide/silica support such as alumina/silica wherein the silica content of the support is from about 2 to about 95 weight percent and the metal oxide content of the support is from about 5 to about 98 percent with (b) a tris(cyclopentadienyl)trinickel dicarbony. This process is characterized by a relatively high reaction rate at moderate temperatures and pressures and results in the production of relatively high proportions of desirable trimer, tetramer, pentamer, and higher olefinic products.

  • Lubricating oil hydrotreating process
    Patent number: 4285807
    Abstract: A lube oil feedstock is subjected to hydrotreating in the presence of hydrogen and a fluorine-promoted catalyst comprising nickel and molybdenum on a support wherein the nickel and fluorine are derived from an ammoniacal solution of nickel fluoride. The catalyst can be prepared by contacting the support with an alkaline impregnating solution consisting essentially of NH.sub.4.sup.+, Ni.sup.++, MO.sup.+VI and F.sup.-, said Ni.sup.++ and F.sup.- being supplied from nickel fluoride, in a single step employing the incipient wetness technique. The impregnated support is thereafter heated to drive off the alkaline component of the solution and thereby deposit the fluorine, nickel and molybdenum on the support.

  • Impregnating solution for hydrotreating catalyst manufacture and production thereof
    Patent number: 4285836
    Abstract: An aqueous, alkaline impregnating solution for the one-step impregnation of fluorine, nickel and molybdenum onto a catalyst support is provided by admixing nickel fluoride, preferably an ammoniacal solution of nickel fluoride and an ammoniacal solution of Mo.sup.+VI to form a compatible impregnating solution consisting essentially of NH.sub.4.sup.+, Ni.sup.++, Mo.sup.+VI and F.sup.-. Nickel and fluorine ions are present in a ratio of substantially 1 to 2. The use of nickel fluoride in a predissolved ammoniacal solution for admixture with the ammoniacal solution of the Mo.sup.+VI renders the resulting impregnating solution highly suitable for impregnation of fluorine, nickel and molybdenum onto a catalyst support by the incipient wetness technique in one-step. The catalyst produced using the present impregnating solution is highly active for hydrotreating lubricating oils.
